Any DPI which can call Python in verilog testbench?

[wilson_on]

Hi, I am new to Python and I have been asked to build a UVM testbench which can call Python functions.  Is there any way that I can do which is similar to DPI-C for C functions in verilog testbench?  If you can provide a detail example, that would be great.

 

Thanks.

Yes.  I can't find it at the moment but some time with Google search should turn up a whole library a guy had written that uses Python as the verification language via the dpi.  Seemed very interesting but I never did more than skim the docs.

You can take a look at cocotb, though I haven't used it.

try this one,

a python systemVerilog DPI wrapper interface by using registered callback events.

A good tutorial to understand how to embedd Python in C

https://www6.software.ibm.com/developerworks/education/l-pythonscript/l-pythonscript-ltr.pdf

Then you can search how to use DPI with C to be able to use C in systemverilog. Sure, There is a lot of DPI examples in your vendor EDA simulator folder.
